Do you have questions before purchasing, want to report a bug or need general help? Please go to the sales page and send me a direct message there. I would like to dedicate this page to future improvements and discussions about the current state of the addon.

Salespage: https://blendermarket.com/products/lens-sim

I think there are room for improvements on this addon, like adding more parameters for better controls, extra features, more lenses etc. I did discover a lot during the initial development, feedback from beta testers has also helped a lot with discovering missing features and general improvements. Having a broader range of people using this addon will shine light on different aspects of the current state of the addon, feedback is key to improvement, so if you have something on your mind feel free to share it here.

Once suggested, I will make a voting poll for new features and lenses:

  • Slider for an easy dolly zoom effect
  • Build 3D mesh from lens

For me it’s quite straightforward to implement a lens. My main issue is finding lenses with a unique design and that’s in the limits of my addon. Aspheres and 15+ lens elements is not supported. Also, it’s hard to find the data table to modern lenses, it seems like they stopped making and publishing patents when replicating lenses became too hard.

A great source for finding lens patents:

WIP update log:

1.0.1:
    
    NB! Due to rewriting the code that detects Lens Sim cameras,
    this version is not backwards compatible with older Lens Sim cameras.
    I had to do this to address some performance issues with the old code.
    
    New features:
    -Added an "Exposure" parameter to the main panel
    -Color Filter, colors is set by a color ramp
    -Prism Filter, bends rays from a custom normal map
    -Generate a 3D mesh from the schematics
    -Camera list:
        Select, set as active, pin, delete and convert cameras from list
    -Zoom lenses
        Implemented support for three zoom groups
        This implementation broke the old aperture setup, added abutton to convert lenses from the
        1.0.0 aperture setup to the 1.0.1 aperture setup.
    
    New lenses:
    -10mm f1.9 Kodak Petzval 1948 Cooke Triplet
    -24-35mm f3.5 Konica Minolta MD Zoom
    -50-135mm f3.5 Konica Minolta MD Zoom
    -35-70mm f3.6 Olympus Zuiko Auto-Zoom
    
    Bugs and fixes:
    -Improved focusing on:
        85mm f1.5 Canon Serenar
        85mm f1.5 Zeiss Biotar
    -Fixed a bug when pressing "Disable Lenses" and "Focus Object" was set to None
        The fallback focus distance is set to 500.0m
    -Object mode is now forced when creating a new lens to avoid error message
    -Fixed typo:
        old: 50mm f2.5 Cannon Compact Macro.txt
        new: 50mm f2.5 Canon Compact Macro.txt
    -Focus Empty does no longer get offseted when unparenting and parenting it to the camera
    -Optimized the code that detects the active Lens Sim camera, improving scene performance

Hi, does this work with other cycles versions, such as K-cycles? The addon looks really nice! Looking forward to trying it out

5

Thanks! I don’t know how K-Cycles works. I’m only using native Cycles nodes and the ray portal material. So if that’s supported I don’t see a reason why it won’t work :thinking: But I don’t have a way to verify it.

What a awesome add-on, just purchased it and here are my very quick tests, easy to use and setting, great job!!

I took the liberty of adding your YouTube video to your top post - it’s truly impressive work, and I’ll post it on BlenderNation too :clap:

reading your notice on BlenderMarket about the rendering speed, I think that it could be useful to give some rough estimation about the differences…I think that the best way could be to show some comparison example where the future customers can see both visual differences and render time differences and also a rough estimation, something like “you could have a difference about 3% to 8% on rendertime”.

Another thing: you wrote " Be sure to read the Documentation section and Tutorials before buying and for a full breakdown of the system and its caveats." but I can’t find the documentation page. Am I blind? :slight_smile:

YES: I’m blind. I found it… sorry

@saikafu
Thanks! I remember seeing your renders with the Jackimorphic Camera Pack, looks great as always!

@bartv
Thanks! That’s awesome :slight_smile:

@marcatore
No worries! The documentation section should answer all you need to know :slight_smile:
(added a hyperlink to the “Documentation” word for convenience)

Are the black friday prices already applied or will there be still a discount?

13

Hi, the black Friday sales has not started.
According to the info I have gotten from Blender Market it will happen today, I just don’t know the specific time it will go live.

I think it will be quite noticeable with some sort of banner and a “30%” off marking on the product. I don’t know the specifics here but my addon is marked for the sale :slight_smile:

Great addon! Thanks!

I have a question, is it a bug that I can’t move the camera closer when I lock the camera to the view and move the viewpoint?

15

Thanks!

The addon is using a orthographic camera to work, if you press this button it will be converted back to a standard blender camera representing the Lens Sim setup as closely as possible:

That should enable moving the camera as normal. To enable the lens setup again just press the button again. Hopefully that will work :slight_smile:

Amazing work on this addon! This adds so much more functionality to blender. I could see this being used even for 2d graphics and animation just for its photo realistic lens effects.

I don’t know if it is possible, but I would love the feature to be able to have a range in focus instead of a single point. I know this isn’t technically realistic, but for some shots I want an entire object perfectly in focus and then everything else can blur into bokeh.

I purchased the add-on for Blender, but in the past I had tried to do something to simulate the lenses, unfortunately I never managed to get anything decent, always rendering problems, the portal you use I don’t know how to use it, however I also visited the optics site, and I saw that there is a huge database of all types of optics, I didn’t understand anything, I hope to be able to interpret something in the future.

Here my first test with Lens Sim.
